6.5. Summary

Objects are a natural way of thinking about the world. JavaScript defines various objects like the document object, window object, image object, the event object, etc. There are properties, methods and events associated with each object. The events and  properties of objects can be manipulated using methods which are called event  handlers, like onClick, OnMouseover

6.3.2. event object

During normal program execution, a large number of events occur, so the event object is a fairly active object, constantly changing its properties.  Whenever an event fires, the computer places appropriate data about the event into the event object – for example, where the mouse pointer was on the screen at the time of the

6.3.1. HTML Events

Not all events are significant to a program.  We can simplify situations to determine which events are significant, and  which events we can leave out.  As we know, HTML provides elements to allow us to create web documents.  We can fill these elements with our own data and display unique web documents.  We can position

6.3. Event Handling

An event is an activity that happens on the web document.  More frequently, multiple inputs are received from the user at once through html form.  The user creates events while interacting  with the DHTML form elements.  Dynamic HTML with the event model exists so that scripts can respond to user interactions and change the page

It facilitates objects to be defined ad used in the documents.  All objects in the real world have attributes such

Object and Events Introduction

Most of the JavaScript programs provided to this point illustrate basic computer programming concepts.  These provide you with the foundation you need to build powerful and complex scripts as part of your Webpages.  This chapter presents a more formal treatment to JavaScript Objects that enables scripts to interact with the elements of an XHTML document.
